PERRY E. KENT, 0F NEW YORK, N. Y., ASSIGNOR TO EDWARD W. LIBI/BY, OF ST. PAUL, MINNESOTA.

Application filed December To all whom 'it may concer/n.'

Be it known that I, PERRY E. KENT, a citizen of the United States, a resident of New York city, county of Bronx, and State of New York, have invented a certain-new and useful Improvement in the way of a Linotype-Matrix Reshaper, of ywhich the following is a specification.

My invention relates to improvements in reshapers for rectifying distorted combinations in linotype matrices, and is particularly an improvement inthe device covered by patent issued to me on June 1, 1909, Number 923,275. The improvement herein consists particularly in improved means for locking the die cap or elevator in a fixed or raised position, While the matrix is being detached or pressed downward out of contact with the reforming segments, and unlocking the die cap or elevator when another matrix4 is in position ready for another operation.

Use of the construction shown in my former patent demonstrated that in that construction the die cap was forced downward by adhering to the matrix and necessitated various eXpedients to bring about removal of the matrix.

In order to make the device fully practical it became necessary to invent means whereby the die cap or elevator could be positively locked or unlocked at the proper time and securely held in place whilethematrix was being detached, and these results are accomplished in my present invention.

Referring to the accompanying drawings, forming part of this specification:

Figure 1, is a perspective view of my reshaper.

Figure 2, is a vertical longitudinal cross section of the same, showing the elevator locked in raised position.

Figure 3, is a similar view to Figure 2, showing the elevator in unlocked lowered position.

Figure 4:, is a sectional view on line e-c of Figure 2. f

Figure 5, is a perspective viewV of the elevator; and y Figure 6, is an elevation, partly broken away, with the locking device forming part of my invention.

Referring to the drawings, A represents a block or base portion of my device, and B represents an elevator or reshaper slidably supported upon the rear of the block g f LrNoTYrE-Mn'rnrx nnsmrniii l 5, 1921. Serial No. 520,108.

A through the medium of the flanges 2, extending into corresponding runways in the block A. The block A is' covered by the top case-hardened plates 3, secured in position by the screws 4, said plates forming a bed during the operation of thedevice, as hereinafter pointed out, and in operation limiting the upward movement of the Slidable member B The member fB, as shown in Figure 5, is formed with an `in wardly projecting part 5, whichV part 5 carries the flanges 2 and stands under the plates 3. vThe downward movement of the` reshaper member B is limited -by the base of the block A, the base of said' block having a rearwardly extending portion 6,posi tioned under the member B.

Held within an opening in the upper end and in front of the member B, is the reshaper head, formed with reshaping teeth 8, the bed rplates 3 being formed with a toothed opening 9, to receive the teeth of the yreshaper head in the sliding operation of the supporting member `-B. The member B is forced into raised position, shown in Figures 1 and'2,`by a coil spring 10, interposed between the bottom of the member and the projecting portion 6 of the base block. e

In order to positively lock the member B in raised position while the vmatrix is f being detached from the reshaper, I provide a locking device comprising a slidable pin 11, positioned in an opening I12in vtheinner face of the member Bj the pinbeing normally pressed outwardly by a coil spring`13 to project beyond the inner face of the member 13, as shown in Figure V5.

The coil spring 13 is preferably inset within' the inner Vend ofthe pin 11, as shown in Figure 6, and the pin is held within the opening 12 by a small shoulder 14, over which the inner wall of the member B is burred to hold the pin in position.

When the slidable member B is in the raised position shown in Figure 2, the locking pin 11 is forced yby the spring 13 into the registering opening 15, extending through the block .Af to lock the slidable member B in raised position. The pin 11 is forced out of the opening 15 to permit the lowering of the member B by the following described mechanism: Slidably supported upon the front ofthe base block A is a finger grip 16, guide pins, 17 being carried by the base block, as shown in Figure 2. The ejec- I tor pin, as shown, is formed with an enlarged inner end 22 upon the side ot the rib 21 opposite the spring.

In use, the matrix to be reshaped is posi-- ti'ned upon the bed plates 9, with the toothed portion ot the matrix positioned between the upper teeth andthe central row of teeth ot the reshaper. inwardlyV the finger grip, the looking pin is forced out of locking position, as hereinbefore pointed out, allowing the member B to be pressed down to reshape the matrix through the medium of the upper,

row Vof teeth of the reshaper. The downward pressure upon the slidable member B then being released, will permit the Y same to be forced into raised position by the spring 10. As the member B passes into raised position, with the pressure upon the iinger grip released, the spring 13 will torce the locking pin 11 into the locking position shown in Figure 2. The slidable member B may thusrbe held locked in raised position to permit the removal o the matrix. By having an upper and lower,

and an inner spaced middle set of teeth upon the reshaper head, the reshaper head may, when desired, be removed by the removal of the bed Vplates and 'reversed in position.

I claim: Y
